| ## ◆ insert() [4/6]
iterator nlohmann::basic_json::insert | ( | const_iterator | pos,
|  | const_iterator | first,
|  | const_iterator | last
| ) |  |
| inline
  Inserts elements from range `[first, last)` before iterator pos. Parameters
  [in] | pos | iterator before which the content will be inserted; may be the end() iterator
  [in] | first | begin of the range of elements to insert
  [in] | last | end of the range of elements to insert
  Exceptions
  type_error.309 | if called on JSON values other than arrays; example: `"cannot use insert() with string"`
  invalid_iterator.202 | if pos is not an iterator of *this; example: `"iterator does not fit current value"`
  invalid_iterator.210 | if first and last do not belong to the same JSON value; example: `"iterators do not fit"`
  invalid_iterator.211 | if first or last are iterators into container for which insert is called; example: `"passed iterators may not belong to container"`
  Returns iterator pointing to the first element inserted, or pos if `first==last` Complexity Linear in `std::distance(first, last)` plus linear in the distance between pos and end of the container. Example The example shows how `insert()` is used. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create a JSON array 9 json v = {1, 2, 3, 4}; 10 11 // create a JSON array to copy values from 12 json v2 = {"one", "two", "three", "four"}; 13 14 // insert range from v2 before the end of array v 15 auto new_pos = v.insert(v.end(), v2.begin(), v2.end()); 16 17 // output new array and result of insert call 18 std::cout << *new_pos << '\n'; 19 std::cout << v << '\n'; 20 } Output (play with this example online):
      "one"
      [1,2,3,4,"one","two","three","four"]
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/insert__range.cpp -o insert__range
